ObjectiveDescriptionPart A (Preparing a film)
Theoretical Values (DMHDIBr was the surfactant used) (0.92 meq v/g)* (2g clay) * (1eqv/ 1000meqv) * (1 mol surfactant/ 1eqv ) * (401.47 g/ 1 mol of surfactant) =0.7387 g of surfactant
0.7387 g/2 = 0.3695 g of surfactant
The beaker left to stay on hot plate for a week. Part D (Fe3O4) coated NaMT
